0000359: Include SMTP From entry to replace fixed From address admin@site_domain for all mail sends

Description

lines 88-89 at classes/libmail.class.php :
//The from clause is fixed for all emails so that the users do not reply to one another
$this->From(w2PgetConfig('admin_username') . '@' . w2PgetConfig('site_domain'), w2PgetConfig('company_name'));

Possible actions:
Add a new config table entry ie mail_from and the required additions in System Admin -> System Configuration -> Email Settings and replace admin_username above
or just use already defined for SMTP auth mail_user entry and also replace admin_username with that.
